蒙古栎食用菌原料林造林试验初报

摘要

Using L9 (34 ) orthogonal design, planting density, fertilization and film mulching were selected as test factors .We investigated survival rate , tree height and ground diameter increment and did some statistical analysis in the second year of the afforestation . The results showed that Quercus monglica grow well when planting four trees in every square meter , big film mulching and no fertilizer . Planting density had significant effects on ground diameter growth , but fertilization and film mulching were not significant effect on ground diameter growth .Film mulching had very significant effects on tree height growth , and planting density and fertilization were significant effects on tree height growth .%采用L9（34）正交设计，选取栽植密度、施肥、覆膜作为试验因素，对造林第2年保存率、树高和地径生长量调查和统计分析的结果表明：采用每平方米栽培4株、覆大膜、不施肥组合方式进行栽培，蒙古栎生长性状最佳。栽植密度对地径生长影响显著，覆膜和施肥对地径生长影响不显著；覆膜对树高生长影响极显著，栽植密度和施肥对树高生长影响显著。
